Subject: USB: serial: allow up to 16 ports per device
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ff0c5703a4b11fca86886e5b7ce40c396bef8381;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

USB: serial: allow up to 16 ports per device

Raise the arbitrary limit of how many ports a single device can claim
from eight to 16.

This specifically enables the upper eight ports of some mxuport devices.
